AGITA'IING DEVICE.

Application filed October 19, 1923. Serial No. 659,456.

'1 his invention relates to agitating devices. More particularly, it relates to devices for imparting to barrels, drums andthej-like rotary motionwhereby liquid in the barrel or drum is slopped'ab'out therein for, say, the purpose of c'eaning-the barrel or drum. Previous devices for this general purpose have been open to various objections :'they did not give sufficient motion .to the drum, were difficult to load, did not have adequate and readily usable arrangements for changing the speed ratios, could not'be lockedin adjusted position so as to positively hold the drum inposition, and-hadvariQus other major faults. I h'avedev isedan agitating device or drumcleaner in which these "men tioned,'a nd various other faults of previous devices are overcome and eliminated.'- It is the object of the invention to provide such adevicep V Withou restricting the invention thereto,

it is described with more particular-reference to-the embodimentshown in the accom-v panying drawings In" t'hese drawings Figure 1 isa front elevation "of'afld evice embodying theinvention, with the *drum frame in position to have a drumplaced therein, and a drum in place ready to be rotated;

Referring now to the drawings, theide are detail views of the vice comprises; ingeneral, a frame 1 of preferably rectangular form borne bythe centrally located journals Qand 3'carried in the pillow blocked and 5' presentedby the machine frame 6. The frame lrotat-ably carries, on its cross bars 7-'and 8,-centrally mounted drum-receiving rests or clamp members 9 and 10 desirably in the form of a dished disc. Of these, the one, 9, is driven by the driving train 111213-14:- 15- l6 17 while the other, 10,is adjustable .to-

5 is a fragmentalcross+sectional ward and from the first to clamp a drum between the members 9 and 10. The frame 1 is driven from the tight-and-loose-belt pulleys 18 on theshaft. The gear 11 of the train isfastupon the frame 6, concentric wit'lrthe shaft 2. With this arrangement, as the frame 1 is driven the drum is rotated upon its short axis,- while at the same time the di am is rotatedon its long axis, since the clamp head 9. is rotated as the gear 12 r0 ls upon the fixed gear 11 during the:rotation-of the framel; With this double motion, any liquid in the drum, as cleaning solution, is effectively carried to all partsof the interior surface of the drum.

I Proceedingnow to a detailed description of the structure :',The clamp head 9 (Figure 3) is concentrically carriedbythe shaft 117 to be driven thereby, in any suitable man ner as by the collar-and-pin 19, theshaft being'journaled at 20 on the web of the channel crossbar '7 and a ball-thrust bearing 21 desirably being used, The shaft ,detachably' carries the spur gear 16 to be driven thereby, The gear 16 is driven from the stationary gear 11 by the gear 12, connecting shaft 13, the gear 14 detaohably carried by the shaft 13, and the gear 15, detachably carried by the stud 22; .Withthis arrangement of spur gears 14, 15 and 16, as distinguished from, say, a shaft drive with mitre and bevel gears, the ratio between the speed of rotation of the short axis and that of the long axis can be changed very simply, it being only necessary to change certain of the gears 14, 15 and 16 instead of having to disrupt and replace the entire drive mechanism as would be the case if a shaft drive with mitre and bevel gears wereused, as in that case not only would the size'of the gears have to bexchanged but also the bearing centers would have to be i changed, requiring the installation of new bearingsandso' forth. To facilitate gear changes in the present structure, the bearing stud 22 for the gear 15' is adjustable longitudinally of the cross bar 7, in the slot 23, and clamped in adjusted position in any usual or preferred manner. v

vThe clamp head 10 (Figure 4) is concen the cross piece 8 of the frame 1. The head 10 carries a socket block 27 rotatable on the bearing end 28 of the spindle 24, the end 28 having a thrust head 28, and a ball-thrust bearing 29 being desirably disposed between the thrust head and the clamp head as shown, Thus the clamp head 10 is rotatably mounted with respect to the frame 1 and 1s adjustable toward and from the head 9 for drum clamping purposes. The spindle 24 is conveniently provided with a hand wheel 30.

A look for the spindle 24 is preferably provided, as a precautionary measure, to hold the drum clamped during rotation. As here shown, such lock comprises (Figures 6, 7 and 8) a hasp 31 hinged to the cross member 8, and a pin device 32. The pin 32 presents a portion 33 to tightly fit in any one of a series of holes 34 about the rim of the wheel 30, and a spring portion 35 to fit about the rim. The pin is provided in any desired way with an enlarged end spanning the slot of the hasp to so retain the hasp; as'hereshown, by way of example merely, a pin 37 is passed closely'through the loop 38 of the pin 32. With the pin 32 in" place in the wheel and projecting through the slot 39 of the hasp, the wheel is held against rotation. The slot 39 in the hasp provides for the pin 32 occupying different vertical heights, in accordance with the dilferent vertical positions of the wheel corresponding to drums of different heights.

In order that the frame 1 may be well balanced for rotation about the axis 23 it is desirable, as indicated in Figure 4, to provide elements to counter-balance the gearing for rotating the drum. Such elements may be of any suitable character and, by way of example, I have indicated lead weighting 46 cast into place in the channel cross member 8.

A fulcrum device is preferably provided to facilitate the placing of the drums in the apparatus. As shown in Figures 1 and 2, the

illustrated device comprises a pair of rollers 40, 40 journaled one at each open side of the frame beyond the periphery of one of the heads 9 01*10 and substantially in the plane of the upper edge thereof, upon cross bars 41, 41 carried by the side members of the frame 1. With this arran ement, when the frame 1 is positioned to ring the clamp head, as 9, having the rollers 40 adjacent it,

in lower position (.as in the drawings), a drum may be fulcrumed on one of the rollers 40, and up-ended to drop into place on the clamp head. This makes loading easy.

When loading the apparatus it is hi hly desirable that the frame 1 be positively eld stationary. To so hold the frame I preferably provide a suitable lock. As here trated, such lock consists of a tongue 42 fulcrumed to the machine frame 6 by the rod 43, the rod 43 having an actuating handle 44, and the tongue, rod and handle forming a species of bell crank. As shown in Figure 1,

the handle '44 is of sufficient length to provide that, as it rests in lowered position, the tongue 42 will be in looking position. The

tongue when in looking position rests be' tween the sides of the channel bar 45 which forms the side bar of the frame 1 (Fig. 5).
